A Bitcoin paper backup that follows best practices for successful recovery
One printable file, recording everything a recovery needs. Not just the seed words.

Why most Bitcoin backups fail
People back up the seed phrase and stop. A seed phrase alone is often not enough to find the coins. Recovery also needs the wallet configuration: the derivation path, the script type, the passphrase if you set one, and for multisig, every co-signer's extended public key.
That configuration usually lives only inside the wallet software. When the laptop dies, the app is discontinued, or someone else is doing the recovering, it is gone. Funds are lost this way far more often than they are stolen.
What it covers
Four sheets per key, filled in by hand. For a single-signature wallet that is everything. For multisig you must also back up the wallet descriptor yourself, which keybackup does not supply.
The guide covers what goes on each sheet, how to print it, and where to store it.
